Quantifying fat, oil, and grease deposit formation kinetics

WATER RESEARCH, 88, 786–795.

By: M. Iasmin n, L. Dean n & J. Ducoste n 

Contributors: M. Iasmin n, L. Dean n & J. Ducoste n 

author keywords: Fat, oil, and grease deposits; Saponification; Sanitary sewer overflows (SSOs); Kinetics; Calcium based saponified solids
MeSH headings : Calcium Chloride / analysis; Calcium Sulfate / analysis; Fats / analysis; Fatty Acids, Monounsaturated / analysis; Hydrogen-Ion Concentration; Kinetics; Rapeseed Oil; Sewage / analysis; Temperature; Waste Disposal, Fluid
TL;DR: This mechanistic saponification model, with its ability to track the saponified solids chemical precursors, may provide an initial framework to predict the spatial formation of FOG deposits in municipal sewers using system wide sewer collection modeling software. (via Semantic Scholar)

Factors that influence properties of FOG deposits and their formation in sewer collection systems

WATER RESEARCH, 49, 92–102.

By: M. Iasmin n, L. Dean n, S. Lappi n & J. Ducoste n 

Contributors: M. Iasmin n, L. Dean n, S. Lappi n & J. Ducoste n 

author keywords: Fat, oil, and grease deposit; Sanitary sewer overflow (SSO); Calcium based fatty acid salts
MeSH headings : Calcium / analysis; Drainage, Sanitary; Fats / analysis; Fatty Acids / analysis; Hydrogen-Ion Concentration; Metals / analysis; Minerals / analysis; Oils / analysis; Rheology; Sewage / chemistry; Spectroscopy, Fourier Transform Infrared; Stress, Mechanical; Temperature
TL;DR: Calcium content in the calcium based salts seemed to depend on the solubility limit of the calcium source and influenced by pH and temperature conditions, which showed that selective removal of palmitic in pretreatment processes may be necessary prior to the discharge of FSE wastes into the sewer collection system.

2011 journal article

Evidence for Fat, Oil, and Grease (FOG) Deposit Formation Mechanisms in Sewer Lines

ENVIRONMENTAL SCIENCE & TECHNOLOGY, 45(10), 4385–4391.

By: X. He n, M. Iasmin n, L. Dean n, S. Lappi n, J. Ducoste n  & F. Reyes  n

Contributors: X. He n, M. Iasmin n, L. Dean n, S. Lappi n, J. Ducoste n  & F. Reyes  n

MeSH headings : Dietary Fats / analysis; Drainage, Sanitary; Environmental Monitoring; Food Industry; Industrial Waste / analysis; Sewage / analysis; Sewage / chemistry; Spectroscopy, Fourier Transform Infrared; Water Pollutants, Chemical / analysis
TL;DR: It is proposed that the formation of FOG deposits occurs from the aggregation of excess calcium compressing the double layer of free fatty acid micelles and a saponification reaction between aggregated calcium and free fatty acids. (via Semantic Scholar)
